Answer:
relatively Easier & Simpler
Step-by-step explanation:
US & Texas constitution have similarities - principles of representative democratic government, bicameral legislature ; civil liberty ; clearly defined & separate powers of legislature, executive judicial govt bodies. {& etc}
However, they are different in regards to amendment process. Compared to amending the U.S. Constitution, the process for amending the Texas Constitution is much easier & simpler.
Proposing amendment is same complex in Texas constitution as US constitution. But, once approved by legislature, it passes simply. US constitution is difficult to amend, resists frequent amendments.
