Ted Cruz’s campaign is claiming a big lead in the Republican US Senate race, with just three weeks to go before runoff election day. According to Roll Call, Cruz led Lt. Governor David Dewhurst by nine points in a recent internal poll. Roll Call also reports sources close to Dewhurst say their polling is quite different, and that their candidate holds a comfortable lead over Cruz.

In the cited poll, 49 percent of 750 likely Republican runoff election voters say they’re voting for Cruz, while 40 percent support Dewhurst. 11 percent haven’t decided. The poll was conducted June 24-26.

"Those within the Cruz camp contend that the jump in Cruz’s polling and name identification is because of the politically engaged nature of the respondents who indicated their intention to vote in the July 31 runoff," Abby Livingston of Roll Call writes.
