US Senator and former GOP presidential candidate John McCain is the latest big name Republican to lend his name to a fundraising pitch for gubernatorial candidate Rob Astorino, touting the Westchester County executive’s tax-cutting record.

In an email sent to potential Astorino donors (and members of the media) today, McCain calls Astorino “a man of honesty and integrity,” and says his record “speaks for itself.”

“As Westchester County executive, he cut or froze the property tax levy each year he has been in office,” McCain writes.

“He also reduced the once-bloated county budget by 5.2 percent over four years by making the commonsense, responsible and tough decisions needed to put the county back on the right track.”

“At a time when many economies were hurting, Westchester saw 30,000 private sector jobs created under the leadership of Rob Astorino. Imagine what he could do at the state level. Rob Astorino is exactly what the Empire State needs, and right now he needs your support.”

The McCain email includes several links to the fundraising page on Astorino’s campaign website.

With this pitch, McCain is following in the footsteps of another ex-GOP presidential contender, former Massachusetts Gov. Mitt Romney; as well as a number of potential 2016 Republican presidential candidates, including Texas Gov. Rick Perry and Louisiana Gov. Bobby Jindal, both of whom have made in-person appearances in New York on Astorino’s behalf.

Other prominent Republicans backing Astorino include former Hewlett-Packard CEO Carly Fiorina and former New Jersey Gov. and ex-EPA Administrator Christine Todd Whitman.

All these efforts highlight the fact that Republican Governors Association Chairman and New Jersey Gov. Chris Christie, another possible GOP candidate for the White House in 2016, has declined to support Astorino’s campaign, saying he doesn’t want to invest in a “lost cause.”
