There may be little drama left in the outcome, but you wouldn't know that by watching the final days of campaigning in the battle for the U.S. House.
Democratic and Republican congressional campaign committees and outside groups for both parties are ramping up spending and committing tens of millions of dollars to those races.
Though Republicans, who control the House by a 242-193 margin, are in good shape to keep the majority, the National Republican Congressional Committee isn't letting up and is on track for record spending -- more than $60 million, according to a committee spokesman.
Underscoring how critical the final weeks of the campaign are, the Republican campaign committee planned to spend $45 million in the six weeks before Election Day. That's the same amount the GOP campaign arm spent altogether in 2010 when Republicans won back control of the House.
Republicans are also getting significant help from outside groups -- several GOP-backed super PACs are targeting races alongside the congressional campaign committee, and they're plugging holes with television ads in some districts where the House GOP campaign arm isn't spending money.
The American Action Network, a conservative policy group, and Congressional Leadership Fund, the Super PAC affiliated with it, spent about $25 million combined in September and October on TV spots, radio, and mail in over 20 House races, mostly defending GOP incumbents.
The YG Action Fund, a super PAC run by former aides to House Majority Leader Eric Cantor, has targeted most of its resources toward helping Republican challengers and has spent $10 million to $12 million to help elect those candidates it believes will be the next generation of GOP leaders.
American Crossroads, the super PAC created by former Bush adviser Karl Rove, has targeted $10 million for House races. The U.S. Chamber of Commerce has also spent millions in support of House Republican candidates.
Democrats, meanwhile, are working to keep pace with their own spending. Despite an open acknowledgement by many Democrats that regaining control of the House is an uphill battle, they're not cutting back on resources.
The Democratic Congressional Campaign Committee and its allies are also dedicating record amounts of money in 2012. The Democratic campaign committee has spent $34 million already, and had a total of $54 million to spend over the course of the campaign.
Last week it took out a $17 million line of credit for the closing days, though a senior Democratic campaign official says it was unlikely the committee would use the full loan.
And while they are quick to complain about the influence of outside money, Democrats are also getting major assistance from groups supporting Democratic candidates.
The House Majority PAC spent $35 million over the 2012 election cycle -- $7 million of which will be spent in the final two weeks.
Andy Stone, the spokesman for House Majority PAC told CNN, "We will make serious gains for sure."
Labor unions, like the Service Employees International Union and the American Federation of State, County and Municipal Employees, are also chipping in for television spots and mobilizing members in targeted races.
Battle being played on narrow playing field
All 435 members of the House face voters on Tuesday, but control of the chamber ultimately rests on roughly 50 to 60 competitive races due partly to redistricting.
The number of swing districts has continued to shrink over the years as GOP legislatures shored up their seats and Democratic-led state houses strengthened their party's districts.
Democrats need to pick up 25 Republican seats to flip control, something that House Democratic Leader Nancy Pelosi repeatedly argues is within reach.
Pelosi conceded Democrats would lose some seats when she told CNN recently that Democrats would need to "net 25 seats," and several veteran campaign analysts said the total number of seats Democrats need to win is between 35 and 40.
Pelosi and other Democrats pointed out that currently there are 58 Republicans representing districts won by Obama in 2008 and hold those up as their blueprint to a successful election night.
But David Wasserman, who analyzes House races for the Cook Political Report, says Democrats are really only waging competitive campaigns in 32 of those districts, which isn't enough to win the House back.
Despite Pelosi's public optimism, multiple other Democratic members and aides say a more realistic goal for the party is to pick up between five and 15 GOP-held seats on election night.
Stuart Rothenberg, an independent campaign analyst, projected last week that Democrats would gain between two and eight seats next Tuesday.
A senior House GOP campaign official told CNN on Wednesday that despite others predicting Republicans will lose seats, they believe they will actually gain between four and six.
