CHARLOTTE -- The official start of the Democratic National Convention isn't until tomorrow, but the Republicans are starting to bait President Obama anyway.

The Republican National Committee debuted a new Web video and launched a website, with the theme of "Obama Isn't Working." The website will be updated frequently while Democrats gather here this week to formally nominate Obama to a second White House term.

"When Americans look back on the past four years under President Obama and ask themselves whether or not they are better off, unfortunately they will answer 'no,' " RNC Chairman Reince Priebus said in a statement.

"President Obama has not lived up to his promises he made to turn our economy around and cut the deficit in half in his first term," Priebus continued. "There are more people out of work today than when Barack Obama took office and 23 million Americans who are out of work or looking for more work."

Expect the GOP to return to the "Are you better off than you were four years ago?" message repeatedly this week. Later today, the RNC will hold its first of several news conferences, as part of its counter-messaging efforts. Priebus and Rep. Jason Chaffetz of Utah, a frequent surrogate for Mitt Romney, will speak to reporters.
