We're in the final days of the Texas Primary runoffs, and there's still no clear picture of how the Republican race for US Senate might shake out. Attorney Ted Cruz and Lt. Governor David Dewhurst continue to duke it out for the nomination, touring the state, flaunting their endorsements and taking shots at each other.

Whether they're attacking Dewhurst's record as a Texas lawmaker, or drawing conclusions on court cases Cruz has tried, outside groups are spending millions to make their opponents look bad.

“Obviously, it’s in my best interest to have as big of a turnout as we can,” Dewhurst told reporters Thursday in Austin.

The candidates are sticking to retail politics as usual, touring the state in advance of Tuesday's runoff, with a dozen stops planned between them, talking about what they'll do different if Texas voters ultimately send them to Washington.

“Now is not a time for compromising our principles. Now’s the time to draw a line in the sand. Now’s the time to stand up and say if we don’t stop spending money, we’re going to lose our country,” Cruz said Tuesday in Waco.

Dewhurst continues to campaign on on what he calls the "Texas Miracle."

"So assuming what he’s saying is true, you could argue that there’s not that much difference between the two of us, other than I’ve done all the things Mr. Cruz says he wants to do,” Dewhurst said.

Their pools of support differ. Cruz is largely Tea Party-backed, and he will be among big Washington names Friday and Saturday with events in Houston and one near Grapevine. Governor Perry will be campaigning all day Monday alongside Dewhurst.
