Sarah Palin is endorsing fellow Republican Pat Toomey in Pennsylvania's Senate race.

In a statement posted Tuesday on Facebook, the former Alaska governor and 2008 vice presidential candidate listed Toomey and a half-dozen other Senate contenders as candidates who deserve support in the Nov. 2 election.

Palin says they all would hold the line against proposed "cap and trade" restrictions on air emissions that she said pose a threat to jobs in industrial and manufacturing states.

The endorsement surfaced just before a poll released Wednesday that shows Toomey's Democratic rival, U.S. Rep. Joe Sestak, gaining ground on Toomey.

A spokesman for the state Democratic Party says the endorsement shows Toomey has more in common with GOP extremists than the people of Pennsylvania.
