Obama does low-key election work

President Obama hasn't made any public campaign appearances since Sunday, but he is working behind the scenes on Election Day efforts.

The president cut a radio spot for Sen. Kay Hagan, D-N.C., who is in a tight re-election battle with Republican Thom Tillis.

He also made a get-out-the-vote conference call with Democrats in Texas, where Democrat Wendy Davis faces an uphill battle against Attorney General Greg Abbott in the race to replace Gov. Rick Perry.

Obama has also recorded get-out-the-vote messages for "robocalls" across the country.

We wouldn't be surprised if there are other calls and radio spots that have been cut, but flown under the radar.

Some Democratic candidates -- especially those in the South -- shunned Obama during the campaign because of his low approval ratings. But many also believe that the president can help generate turnout among long-time Democratic constituencies, including African-Americans and single women.

On Tuesday morning, Democrats received an e-mail signed by Obama, reminding them that it's Election Day:

"If you don't vote today, you're letting someone else decide the future for you.

"You're letting someone else pick a reality that will shape your life for two years. Today is just that simple.

"So don't let it happen ...

"Confirm your polling place, and make sure you and your friends and family are the ones deciding the future."
