In one of his famous songs, "Changes," David Bowie sang: "Where's your shame, you've left us up to our necks in it." This lyric seems just as appropriate today as it did when he first published the lyric in 1971.

Our leaders in Washington, D.C. have done little this year other than bicker, obstruct the legislative process, and stir controversy on Twitter. All this is happening as the world is becoming an even more dangerous place—North Korea has ICBM capabilities, Syria continues to murder its own people, and millions of Americans are suffering without adequate healthcare.

Both parties are to blame. When I study history, there are always inspiring leaders that become the icons of their time—today, there are no heroes in Washington.

The last week has been particularly disappointing. After 8 years of criticizing Obamacare and even putting legislation on Obama's desk to repeal the Affordable Care Act (which was promptly vetoed), the Republican-controlled Congress has not fulfilled its most central campaign promise—reform healthcare.

In addition, President Trump, who promised to protect the LBGTQ community when on the campaign trail, has now unilaterally banned transgender individuals from serving in the military. Infighting and leaks within Trump's White House staff have created even larger distractions and provided unparalleled fodder for light night television.

All the while, our nation's problems continue to grow without any real solutions on the horizon.

Just when I thought Washington could not get any worse, our elected officials found a way to sink even lower.

As a lifelong conservative and registered Republican, I made a difficult decision this past week. I revised my party affiliation.

My disgust crosses party lines—Democrats such as Hilary Clinton, Nancy Pelosi, and Chuck Schumer represent all that is wrong with politics. Self-serving, out of touch long-time politicians who care more about their own personal gain than those who they supposedly represent.

The Republicans who promised immediate action if they were given the power to pass legislation have instead given voters the biggest bait-and-switch in history. Rather than focus on moving on important legislative matters, both Republican-controlled chambers of Congress have simply stalled any progress due to intra-party disagreements.

Ultimately, those in Washington need to be held accountable for their inaction. No longer should voters focus on a two-party system and work towards protecting a majority or voting along party lines.

Each of us must carefully evaluate the job our leaders are doing and clearly call them out on any missteps. When members of Congress are up for re-election in our districts, and when it is clear that they have not worked to move our country forward, we must vote them out.

As voters, we can impose our own term limits on Congress. No longer do we have to tolerate the same disgusting politicians every single year.

We have the ability to invoke change. As David Bowie sang, "Time may change me, but I can't trace time." Simply put, we don't have to retrace the past in Washington year after year—vote for change.
