It seems like we've been talking about the Texas primaries for a year, but this week voting finally began. And campaigns are uglier than ever.

The top two Republican contenders for U.S. Senate aren't pulling any punches and its tough to watch TV these days without catching a negative campaign ad. It seemed to us, the attacks and rhetoric have overshadowed the issues central to each campaign.

We decided to do an audit of the campaign websites of David Dewhurst, Ted Cruz, Tom Leppert and Craig James. Despite the men spending much of their time differentiating themselves from the pack, we found many similarities, especially between the top two contenders.

"Obamacare" tops the list for Former Solicitor General Ted Cruz and Lt. Gov. David Dewhurst's. Both also address what they describe as the Environmental Protection Agency's "job-killing regulations."

Former Dallas Mayor Tom Leppert and Former ESPN Analyst Craig James' priorities run parallel. Both rank federal spending as their top priority, saying if they get to Washington they'll propose a Balanced Budget Amendment. James and Leppert are also the only candidates who address social issues on their sites. James is the only candidate who lists foreign policy concerns.

The candidates do differ in some key ways. Dewhurst offers some specifics on how he'd address four main issues; as do Leppert and James. Cruz's, on the other hand, outlines what he thinks is wrong with Washington, but doesn't offer any solutions.
