Texas Gov. Rick Perry is now the clear front-runner for the Republican presidential nomination.
Recent polls show him with a significant lead over the other candidates. But how long can Perry stay on top?
Perry burst into the GOP field a few weeks ago, dramatically altering the battle for the Republican presidential nomination.
A new CNN poll shows 27 percent of Republicans support him as their nominee.
Former Massachusetts Gov. Mitt Romney trailed with 14 percent of likely supporters, while Rep. Michele Bachmann fell in third with only 9 percent.
Perry began outlining his foreign policy to thousands of veterans this week in San Antonio. He's trying to strengthen his foreign policy credentials.

Perry has reached out to former Defense Secretary Donald Rumsfeld and other Bush administration veterans for advice.
"We must renew our commitment to taking the fight to the enemy wherever they are before they strike at home," he said during a campaign stop.
But it's Perry's economic record in Texas that excites mainstream Republicans.
Tea Partiers rally around his tough talk on entitlements like social security.
"I can promise you my 27-year-old son, social security under the program that we have today will not be there," Perry said.
Romney was the GOP favorite before Perry came into the race. He's now campaigning in Perry's state, but isn't focusing on the governor.
Instead, Romey's attention is on President Obama.
"It's been a presidency which has been associated with debt, and with downgrade, and with delay," Romney said.
The next two months will big for Perry. There are five GOP presidential debates and several upcoming events likely to attract the candidates.
