The Democratic Party has become the party of resistance. They have no solutions, only resisting Trump at every opportunity. It wouldn't matter if Trump found the cure for cancer, he would be resisted.
I am neither a Democrat nor a Republican. From my perspective ( independent view) , both parties have become parties of resistance. Republicans seldom worked with President Obama in his second term. Democrats did the same during President Trump's last term. Under President Biden, despite 2-3 major bipartisan bills passing, nothing achieved since Republicans regained control of the House. It remains to be seen if Democrats will collaborate with President Trump. I assume they will not.
Regarding criticism, I recall when President Obama was in office. Right-wing cable TV and radio would refer to him as "Barack Hussein Obama," often emphasizing the middle name "Hussein" to suggest he was Muslim. The current President of the United States questioned President Obama's citizenship for eight years. Republicans labeled President Obama a socialist and accused him of associating with terrorists.
When President Trump took office, Democrats criticized him harshly, labeling him as authoritarian and expressing concerns about the end of democracy. They often criticized his tweets, speeches, and spontaneous comments. Left wing media outlets have been critical of President Trump since he took office. Even though it has not been a month since his inauguration, some are already questioning, "Where is the resistance, Where is the resistance?"
During President Biden's four years in office, the sitting president of the United States did not acknowledge that President Biden won the election. More than 40% of Republicans couldn't admit Biden's victory. Fox News paid over $700 million for false election claims.
Please refrain from claiming that Democrats are the party of resistance and Republicans are the party of solutions. Both parties have their similarities.
