NEW YORK STATE -- It's that time of year again. Every fall on even numbered years, TV viewers are bombarded with a bevy of advertisements for and against a candidate. As both Republicans and Democrats battle for control of the House of Representatives, it will be independent voters who will be targeted.

“Twenty-five to 40 percent of the voters, depending on the Congressional district, are what we call the swing voters. They're the voters who determine the outcome of elections. They are also the voters that tend to pay the least attention to politics until it gets closer to the end,” said Steve Greenberg, Siena College Poll Spokesman.

Each ad has its own goal. For GOP Congressman Chris Gibson, he needs to introduce himself to a new set of constituents after his district changed during redistricting.

The Democratic Congressional Campaign Committee, meanwhile, attacks incumbents like Anne Marie Buerkle.

Outside groups are expected to pour millions of dollars into advertising, including the so-called Super PAC Crossroads GPS run by Republican operative Karl Rove. His group will invest in the first congressional district race between incumbent Democrat Tim Bishop and GOP candidate Randy Altschuler.

Greenberg said, “I don't think voters can distinguish between a Bishop ad, a DCCC ad or an independent expenditure on his behalf ad.”

With so many competitive seats stretching from Western New York to Long Island, the state is a battleground for control of the House. Republicans hope that an extensive get out the vote effort will blunt what is expected to be a significant Democratic turnout in a Democratic heavy state during a presidential election year.
