Yes, I could do a much better job.
Why? do you doff your cap to all of your superiours? and it sounds like you have many. Get off your knees man, lead your own life, stop letting others lead your life for you.
And please, list some of your favorite politicians.
Let's stick to the current British Cabinet (23 members) to keep it manageable. Of them, I am satisfied that the following have carried out their duties acceptably since the 2010 general election: David Cameron, Nick Clegg, George Osborne, William Hague, Vince Cable, Eric Pickles, Baroness Warsi, Jeremy Hunt, Caroline Spelman, Andrew Mitchell, Lord Strathclyde, Ken Clarke, Owen Paterson, Michael Moore, Danny Alexander, Cheryl Gillan and Iain Duncan Smith.
Theresa May, Michael Gove and Andrew Lansley are not on the list because the first has been incompetent and the other two advocate core policies (in education and healthcare respectively) that I disagree with.
(Ed Davey, Justine Greening and Philip Hammond have not been in the Cabinet long enough to judge, but I am confident they will do their jobs well.)
17/20 is not a bad hit rate. There are plenty of other British MPs outside of government that I respect, and many foreign politicians too.
I do not think of these people as my "superiors." They are people just like you and me, no better, no worse. However, they are certainly better qualified to be politicians than I am. It is a thankless job and it is a tough job. If they want to subject themselves to public scrutiny to serve the country's best interests then good for them. I neither want to be a politician nor think I have the skills to do it.
Now I'm expecting you to post the qualifications, experience and achievements that make you better for the job of leading this country than those already in office. Unless of course you're just like every other average Tom, Dick and Harry, gobbing off down the pub because he has nothing better to do.
