With President Obama's poll numbers in a free fall and his strategy of disengagement on major issues, some Republican presidential hopefuls are stepping up.

The man taking the most advantage of the situation is Texas Governor Rick Perry, who has now become Mr. Obama's primary adversary.

GOV. RICK PERRY (R-TX): "Well, it's same the president who said al Qaeda is on the run. And you know, I don't know whether he's inept or there's something else going on, as I've said before, but the fact is the border is not secure. We have a humanitarian crisis on our hands now because the border is not secure. And the president needs to understand that the single most important thing that he can do is put the National Guard on the border to coordinate with local law enforcement, with our state law enforcement with the border patrol."

Governor Perry is clearly looking to run in 2016, and with a good economic story in Texas he has a solid foundation.

Possible candidate number two may surprise you.

It's Mitt Romney. Some of his acolytes are whispering that he is considering another presidential run.

And The Factor has learned, that this is not idle talk.

Recently the Romney family held a big gathering on Mackinac Island in northern Michigan.

They stayed at the Grand Hotel up there, a very nice place, and there was much talk about Governor Romney running again.

New York Post columnist Cindy Adams reports that Mr. Romney may well do that, and Ms. Adams has been right before in political predictions.

Talking Points would not be surprised if Mitt Romney steps up.

The third possible candidate taking advantage of the southern border situation is Texas senator Ted Cruz.

SEN. TED CRUZ (R-TX): "Apparently playing a game of pool is a higher priority for this president than it would be to go and see the humanitarian crisis he's created. The president's right in one regard. He's described what is happening on the border as a humanitarian crisis, and it is, but it's a crisis of the president's own creation."

Mr. Cruz is obviously the darling of committed conservatives, and he is certainly looking at a presidential campaign.

Some other possible candidates have not been as vocal on the border crisis: Senator Rand Paul from Kentucky and Jeb Bush to name two.

So you can expect over the next six months to see the Republican candidates become more visible, vocal, and more critical of President Obama.

By early next year, the candidates must be out raising money if they want to compete with Hillary Clinton -- who is a lock for the Democratic nomination and therefore will not have to spend a lot of money securing it.

The border has given republicans an opening, pardon the pun, and there's no question some GOP folks are crossing into presidential competition.

And that's the memo.
