The intervention of Kelivin McKenzie - apparently backed by the Sun and with financial support from Murdoch, if the BBC report is accurate - makes this potentially very interesting.
McKenzie's position is described by the BBC as being as follows:
But Mr MacKenzie said it was "rubbish" that "we are living in a controlled state".
"Personally I'm very grateful that there is CCTV around everywhere and I'd like more of it," he said.
"Most of us are not bad guys, we have nothing to fear."
He also told the BBC he would be campaigning on three issues, hostility to the "sense that our country is somehow in the grip of some kind of security vice", demanding that there be "the referendum for Europe", and on more populist issues - like seeking changes to government spending on "things I don't think we care about".
So, as well as the civil liberties issues, we've got that old chestnut, Europe, and a rag-bag of issues which, given McKenzie's record as an editor, are likely to be the usual issues; so-called "political correctness", immigration, opposition to public service broadcasting (if there's Murdoch money involved, you can guess where this is heading).
All of which suggests the interesting spectacle of a Tory - and one who, in his role as Shadow Home Secretary is no stranger to populism - taking a stand on civil liberties and being opposed from the position of the old populist right, by a man whose decision to stand appears to be motivated by the absence of New Labour.
So, whatever the motivation behind the events, the outcome could be a lot more interesting - and important - than would have been the case before McKenzie's intervention. If Davis wins, and wins well, one could see this as a firm rejection of the odious values behind
The Sun and other right-wing tabloids - something which I, for one, would cheer long and loud. If it's closer - or even if, God helps us, McKenzie wins - then there is a real battle on our hands between the values of liberal tolerance and a poujadism which is barely distinguishable from the position of a party that we don't name here, but has recently got its first London Assembly member and regularly gets more than ten percent of the vote in local by-elections. McKenzie could be a stalking-horse for the values of the unnamed party.
So my feeling is that if McKenzie does stand, this could be a political event whose significance could be much greater than Davis might have realised, for rather different reasons.
