Republicans in Texas faced another setback on Sunday in their attempts to stop votes from being counted.<br />CNN reports the Texas Supreme Court denied a petition by a group of Republicans seeking to invalidate more than 120,000 drive-thru votes in Harris County.<br />It's the second time in recent weeks the state Supreme Court has blocked attempts to dismantle drive-thru voting there.<br />Curbside voting in Harris County is limited to voters with a disability and is located at all polling sites.<br />However, ten of Harris County's 120 early voting sites are drive-thru locations. The drive-thru voting locations are open to all voters.<br />The latest state and federal challenges argue that drive-thru voting violates the US Constitution, which says state legislatures decide how elections are run.
