Thirty-one House Democrats, most of whom face tough re-election bids this fall, have signed a letter to House Speaker Nancy Pelosi and House Majority Leader Steny Hoyer urging them to extend expiring tax breaks for all income levels, including the wealthy.

Pelosi and other House Democratic leaders have made it clear they support President Obama’s proposal to vote on a bill that only renews tax breaks for those making $250,000 and under. But with the midterm elections less than two months away, leaders have not yet decided whether they will schedule a vote on the legislation before voters go to the polls.

The letter–written by Utah Rep. Jim Matheson, Illinois Rep. Melissa Bean, Virginia Rep. Glenn Nye and Michigan Rep. Gary Peters–states that after listening to economists, small businesses and families over recent weeks they are concerned that “raising any taxes right now could negatively impact economic growth.”
