Pat Toomey and Joe Sestak are going head-to-head for their second and final debate tonight, this time in Pittsburgh. They met earlier this week on Wednesday, in Philadelphia’s National Constitution Center. Tonight’s debate will broadcast live at 7 p.m. on Pittsburgh’s WPXI and will be streamed live on their website.

The Washington Post reports:

With the race so close, national party committees, business advocacy groups, labor unions and more are pouring millions of dollars into the state in TV ads and get-out-the-vote efforts to influence the outcome.

Indeed, it appears both campaigns are fundraising furiously in an effort to drive home their message in the final days. And with President Obama coming back to Philadelphia on Oct. 30, it’s clear Sestak is running explicitly on the message: “Vote for me, help the president.”

Sestak is, after all, the president’s “strongest ally.”

In response to Joe Sestak demurring on abortion in Wednesday’s debate, saying he couldn’t place it in a moral context and calling it merely a “private decision,” one Battle ‘10 reader wryly noted:

Some people seem to have a very flexible definition as just what constitutes a “private decision”. Whether or not to have an abortion is a private decision. Whether or not to buy health insurance apparently, is not.
