Final answer:
After the 2002 elections, the Republican Party held all statewide offices and the majority in both the Texas House and Senate, largely due to successful redistricting efforts and a national trend towards Republican gains in various levels of government.
Step-by-step explanation:
The Republican Party held all statewide offices and the majority in both the Texas House and Senate following the 2002 elections. This success was part of a larger national trend where the Republican Party made gains in both the Senate and the House of Representatives, as well as in most governorships and state legislatures across the country. This marked a significant political shift in Texas, which had previously been a stronghold for the Democratic Party.
In the aftermath of the 2000 presidential election, the Texas legislature, controlled by a majority of Republicans, redistricted the state in 2003. This redistricting plan, which included changing the U.S. congressional districts covering Travis County, diluted the voting power of this heavily Democratic area, contributing to the Republican dominance in the state.
Nationally, after the 1994 elections, the Republican Party took control of both the House and the Senate for the first time in over forty years. The redistricting in Texas, coupled with broader national trends, helped solidify Republican control in the state after the 2002 elections.
