A day after launching an attack ad against New Hampshire Rep. Charles Bass, two liberal groups have released new polling that suggests the Republican is deeply unpopular just seven months after his election.

If the numbers are correct, the Congressman’s vote in favor of the Medicare overhaul in the House GOP budget could become a political liability next fall.

Just 29 percent of likely voters in New Hampshire’s 2nd district approve of Bass’ job performance, according to a survey conducted May 31 and June 1 by the Democratic firm Public Policy Polling on behalf of Democracy for America and the Progressive Change Campaign Committee. The margin of error for the poll, obtained by Roll Call for an early look, was 4.2 points.

When asked about Medicare, 2nd district voters offered a similar sentiment as those of New York’s 26th district, who gave now-Rep. Kathy Hochul (D) an upset victory in last month’s special election. She won at least in part because her Republican opponent supported Medicare cuts in the House Republican budget plan written by Budget Chairman Paul Ryan (Wis.).

Sixty percent of New Hampshire respondents said they oppose cutting Medicare. And 69 percent said they support raising federal taxes on those with incomes over $250,000 a year “to save programs like Social Security and Medicare from cuts.”
