Sunday shows preview: Republicans talk strategy as midterms approach; Iran conflict, Canada trade war leave economy in flux

Republican leaders convened in Dallas this week for a two-day midterm convention to solidify the party's campaign strategy ahead of the November elections. The event emphasized a President Trump-forward approach as the party works to retain its majority in both chambers of Congress.

These political preparations occur against a backdrop of economic uncertainty. National economic stability is currently being tested by ongoing tensions involving Iran and a developing trade dispute with Canada, both of which are contributing to a volatile financial climate.
