There is increasingly smaller differences between them and the lefties. It is now just a (small) matter of degree.
Sadly, that is true.
The lobbying industry is mostly to blame in this regard. With our unending cycles of elections, most politicians spend more time campaigning than they do actually governing. As a result, they have to perform more fundraising. The natural tendency is for them to accept money from donors who have vested interest in the status quo.
They used to say that the Republican party was the party of business while the Democrat party was the party of the people. Both parties are now the parties of business. The people are often simply just instruments to serve the corporate agenda.
And I am not some naysayer out against the corporations. Lobbying comes from all sides including unions, religious affiliations, the medical establishment and our seemingly endless supply of attorneys.
