Over the last decade, two Republicans with the last name Perry have dominated the Texas political landscape. One is Rick, the state’s longest-serving governor. The other is Bob (no relation), the state’s largest individual political donor during that time — with no close second. Since 2000, the wealthy Houston home builder has contributed about $28 million to more than 400 candidates and political action committees in Texas, according to an analysis of campaign-finance data by The Texas Tribune. During that time, he's also contributed at least $38 million more to candidates and groups outside of Texas.
