Mitt Romney is expected to clinch the Republican presidential nomination tonight with a victory in the Texas Republican presidential primary.
Texas has 152 delegates at stake, and Romney is 60 short of the 1,144-delegate majority needed to win the GOP nod, according to the Associated Press.
Romney has been considered the presumptive nominee for weeks as he has continued to win primaries and as his major opponents, including former House Speaker Newt Gingrich of Georgia and former Sen. Rick Santorum of Pennsylvania, have dropped out.
Rep. Ron Paul of Texas is the last serious candidate besides Romney in the GOP race but he is far behind in delegates and isn't expected to come close to Romney in Texas.
Romney, the former governor of Massachusetts, has been trading charges and criticisms with President Obama as each one maneuvers for the fall election. Various polls indicate a close race, and some surveys indicate that the two candidates are in a statistical tie.
