the reason texans thought that northern states violated the constitution was because the northern states wouldn't return runaway slaves.
Zachary Taylor was the future US president who won the battle of buena vista in 1847 during the Mexican-American war against Mexico. He was the 12th president who died within 16 months into his presidency before he could make any true presidential progress.
I believe it is the first choice: The new regulations caused investors to lose money on their stocks.
It would be an example that shows it is important to vote because the president has executive powers that allow him/her to appoint a justice which is a lifetime appointment and is a very very powerful position, so choosing a right president could affect many things.
Hope this helps!
Good day to you.
