Another group, Iowa Progress Project, has spent $200,000 airing anti-Cruz ads. "Rick Santorum spent his time in the Senate a little differently". Ted Cruz and Rand Paul stand out as the "bad" candidates on the renewable fuels report card, while the rest of the candidates on both sides of the aisle are graded as "good".
Like some other Republican hopefuls, Santorum is saying foreign-policy experience is vital if the next president is going to lead during a time of terrorism and turbulence in the Middle East.
A former spokeswoman for ex-Arkansas Gov. Mike Huckabee has joined Ted Cruz's presidential campaign, giving the Texas senator a key operative who worked for the last two winners of the Iowa caucuses.
Sen. Ted Cruz famously read Dr. Seuss'Green Eggs and Ham during a 21-hour talk-a-thon on the Senate floor in 2013, providing an easy target for his 2016 rivals.
The ad notes that Santorum has been "a leader taking on radical Islam", but does not clarify as to how.
The ad goes on to suggest that "if you want someone to read you one helluva bedtime story", Cruz is "your guy".
According to the newest polling date made available to us by Real Clear Politics, former Pennsylvania Senator Rick Santorum is faring badly. If you want to protect America and defeat ISIS, Rick Santorum's your president.
The ad doesn't have a wide buy in Iowa or New Hampshire, but the Santorum campaign did share it through its social media network. This year, though, most polls show Cruz is ahead there.
Like Huckabee in 2008 and Santorum in 2012, Cruz is benefiting from the support of evangelical voters in Iowa. Iowa holds its GOP caucuses on February 1.
